- The present invention relates to an accelerator pedal operation device for transmitting an amount of depression of an accelerator pedal to an accelerator stroke sensor.
- 2. Description of the Related Art
- Ordinarily, in vehicles and the like on which an electronically controlled engine is mounted, an amount of depression of an accelerator pedal is transmitted to an accelerator stroke sensor, an electronic signal corresponding to the amount of depression of the accelerator pedal is generated, and an engine is controlled in response to the electronic signal.
- Conventionally, a cable has been used as means for transmitting the amount of depression of the accelerator pedal to the accelerator stroke sensor.
- Ordinarily, the accelerator pedal is installed in a front narrow portion on a floor of a driver's cabin. For this reason, when the cable is employed as the means, a job for wiring and connecting the cable is troublesome and an efficiency of the job is deteriorated. Further, since there is a possibility of breakage and the like in the transmission means composed of the cable, its reliability is low.
- Accordingly, recently, a system for transmitting an amount of depression of an accelerator pedal to an accelerator stroke sensor through a link mechanism is employed as found in, for example, Jpn. Pat. Appln. KOKAI Publication No. 7-150987.
- Incidentally, an accelerator pedal is provided with an accelerator switch for detecting whether or not the accelerator pedal is depressed. Conventionally, since the accelerator switch has been arranged on a floor of a driver's cabin adjacent to the accelerator pedal, not only an accelerator switch assembly job is troublesome but also the accelerator switch may stand in the way of operation of the accelerator pedal.
- An object of the present invention, which has been made in view of the above point, is to provide an accelerator pedal operation device in which an accelerator switch can be easily and effectively installed in a narrow space of a driver's cabin together with a link mechanism such that the accelerator switch does not disturb operation of the accelerator pedal at all.
- In an accelerator pedal operation device according to an aspect of the present invention having a pedal lever which turns in response to depression of an accelerator pedal, a link mechanism having a reverse lever, which turns in association with the pedal lever, and is arranged as a unit structure, an accelerator stroke sensor which detects an amount of rotation of the reverse lever of the link mechanism and controls an amount of fuel injected into an engine, and an accelerator switch assembled to the link mechanism integrally therewith, the accelerator switch detecting whether or not the accelerator pedal is depressed in association with the pedal lever.
- A preferred aspect of the present invention wherein the pedal lever having a boss portion which acts as a center of rotation, and a first lever and a second lever which extend from the boss portion in two directions, wherein the reverse lever is coupled with an extending extreme end portion of the first lever, and the accelerator pedal is coupled with an extending extreme end portion of the second lever, and an operation unit is arranged on a side opposite to the extending extreme end portion across the boss portion, the operation unit operating the accelerator switch.

FIG. 2 is a side elevational view showing a state in which an accelerator pedal of the accelerator pedal device is depressed. -
FIG. 3 is a perspective view showing a link mechanism of the accelerator pedal device. -
FIG. 4 is a side elevational view showing an accelerator switch of the accelerator pedal device. - An embodiment of the present invention will be described with reference to the drawings.
- As shown in
FIGS. 1 and 2 , apedal holder 3 having anaccelerator pedal 2 is installed on a floor of a driver'scabin 1 of a vehicle. An end of theaccelerator pedal 2 on one end side is upward and downward turnably attached to thepedal holder 3 through ashaft 4. Thepedal holder 3 is provided with astopper 5 for adjusting a maximum stroke width of depression of theaccelerator pedal 2. - Note that
FIG. 1 shows a state before theaccelerator pedal 2 is depressed, andFIG. 2 shows a state when theaccelerator pedal 2 is depressed up to the maximum stroke width. - An
accelerator stroke sensor 7 and alink mechanism 8 associating with theaccelerator stroke sensor 7 are arranged to a front upper portion of the driver'scabin 1. As shown inFIGS. 1, 2 , and 3, thelink mechanism 8 has abase 10, and areverse lever 11 and apedal lever 12 are turnably attached to thebase 10 throughshafts - The
reverse lever 11 is bent to a C-shape, theshaft 13 is inserted into the bent portion, and thereverse lever 11 turns about theshaft 13. Thepedal lever 12 has aboss portion 15, theshaft 14 is inserted into theboss portion 15, and theboss portion 15 turns about theshaft 14. - A
first lever 16 extends in one direction and asecond lever 17 extends in the other direction from theboss portion 15 integrally therewith, respectively. Further, a projecting-piece-like operation unit 18 is arranged to a side opposite to thesecond lever 17 with respect to theboss portion 15 integrally with thesecond lever 17 so as to extend in a direction opposite to thesecond lever 17. - A
spring 20 is assembled to theboss portion 15, and thepedal lever 12 is elastically urged by thespring 20 counterclockwise in the figure in its entirety. - The end of the
first lever 16 of thepedal lever 12 on an extreme end side is coupled with an end of thereverse lever 11 on one end side through apin 22. Thepin 22 is attached to the end of thefirst lever 16 and loosely fitted to a slot (not shown) formed to the end of thereverse lever 11. Consequently, thereverse lever 11 is turned about theshaft 13 in response to the turn of thepedal lever 12. - The
second lever 17 of thepedal lever 12 extends into the driver'scabin 1, the end of theaccelerator pedal 2 on a free end side is placed on and fitted to the end of thesecond lever 17 on an extreme end side, and thepedal lever 12 is turned in response to depression of theaccelerator pedal 2. - The
accelerator stroke sensor 7 has aswingable operation lever 25, and an end of theoperation lever 25 is turnably coupled with an end of thereverse lever 11 on the other side through apin 26. Thepin 26 is attached to the end of theoperation lever 25 and loosely fitted to aslot 24 formed to an end of the reverse lever and shown inFIG. 3 . Consequently, theoperation lever 25 is swung in response to the turn of thereverse lever 11. - A
bracket 27 is attached to thebase 10 of thelink mechanism 8, and anaccelerator switch 28 is attached to thebracket 27 so as to confront with theoperation unit 18 of thepedal lever 12. - As shown in
FIG. 4 , theaccelerator switch 28 has ashaft portion 30 extending from an upper portion of amain body 29 upward together with it, and theshaft 30 is inserted into a throughhole 27 a formed to an end of thebracket 27 from under it. - A
screw 30 a is formed around the outer peripheral surface of theshaft portion 30, a pair ofnuts screw 30 a, thesenuts bracket 27 so as to clamp it, and theaccelerator switch 28 is tightly attached to thebracket 27 by tightening thesenuts nuts - The
accelerator switch 28 has aswitch button 33 at an upper end portion of theshaft portion 30, and theswitch button 33 is urged so as to elastically project upward and arranged so as to confront with theoperation unit 18 of thepedal lever 12. - Note that the
accelerator stroke sensor 7 and theaccelerator switch 28 are electrically connected to an engine control unit (not shown) for controlling an amount of fuel injected into an engine. - In a free state in which the
accelerator pedal 2 is not depressed, theoperation unit 18 comes into contact with theswitch button 33 of theaccelerator switch 28 by elastic force of thespring 20 assembled to theboss portion 15 of thepedal lever 12, thereby theswitch button 33 is pushed downward with predetermined pressure and theaccelerator switch 28 is kept in a turned on state. - When the
accelerator pedal 2 is depressed downward from the engine idling state, thepedal lever 12 is turned clockwise in the figure about theshaft 14 against thespring 20. Thereby, theoperation unit 18 of thepedal lever 12 is released from theswitch button 33 of theaccelerator switch 28. Theswitch button 33 is switched from the turn on state to a turn off state, thereby depression of theaccelerator pedal 2 is detected, and a signal of depression is sent to the engine control unit. - Further, the
reverse lever 11 is turned counterclockwise aboutshaft 13 in association with the clockwise turning operation of thepedal lever 12 and theoperation lever 25 of theaccelerator stroke sensor 7 is swung by the turning operation, thereby an amount of turn of thereverse lever 11 is detected, and a signal of detection is sent to the engine control unit. - Since the signal from the
accelerator switch 28 and the signal from theaccelerator stroke sensor 7 are sent to the engine control unit as described above, an amount of fuel injected into the engine is controlled through the engine control unit. - An amount of depression of the
accelerator pedal 2 is proportional to an amount of swing of theoperation lever 25 of theaccelerator stroke sensor 7 and theoperation lever 25 is swung at a stroke according to an amount of depression of theaccelerator pedal 2, thereby the amount of fuel injected into the engine is controlled to a proper amount. - Incidentally, when the
stroke sensor 7 does not act normally due to a fault and a predetermined signal is not output regardless of whether theaccelerator pedal 2 is depressed and a signal of theaccelerator switch 28 is output to the engine control unit therefrom, the amount of fuel injected into the engine is adjusted to such a degree as to cause the vehicle to travel at a very slow speed under the control of the engine control unit. - As described above, the
accelerator switch 28 is a member for detecting whether or not theaccelerator pedal 2 carries out a depression operation. However, in the embodiment, theaccelerator switch 28 is assembled to thelink mechanism 8 integrally with it and arranged to the front portion of the driver'scabin 1 spaced apart from theaccelerator pedal 2, and therefore, it does not disturb operation of theaccelerator pedal 2 at all. - Further, the
accelerator switch 28 is assembled to thelink mechanism 8, which transmits the stroke of theaccelerator pedal 2 to theaccelerator stroke sensor 7, integrally with it and arranged as a unit. Accordingly, it is not necessary to carry out a troublesome job for attaching theaccelerator switch 28 to a narrow space in the driver'scabin 1 as a single unit, and it can be easily and effectively installed in the driver'scabin 1 together with thelink mechanism 8. - The
accelerator switch 28 must be arranged at a position having a predetermined proper height based on thepedal lever 12 as a standard. That is, it is important to adjust theoperation unit 18 of thepedal lever 12 such that it properly comes into contact with theswitch button 33 of theaccelerator switch 28 in idling as well as being securely released therefrom when theaccelerator pedal 2 begins to be depressed. However, theoperation unit 18 can be easily adjusted by moving theshaft portion 30 up and down by loosening the nuts 31 a and 31 b. - Note that the present invention is by no means restricted to the above embodiment and can be embodied by appropriately modifying the components of the present invention such as the pedal lever and the reverse lever within a range that does not depart from the gist of the present invention.
- According to the present invention, the accelerator switch can be easily and effectively installed in the narrow space of the driver's cabin together with the link mechanism , and also does not disturb operation of the accelerator pedal at all.
